20080116987 - Method and system for spur supression in modulators: An IF receiver receives a tapped portion of a modulated communication signal. A processor, local with respect to the IF receiver, receives an interrupt from a main processor instructing it to evaluate the power levels of desired and undesired components of the communication signal. The interrupt may be sent for... Agent: Arris International, Inc

20080100393 - Low power direct conversion rf transceiver architecture and asic and systems including such: A direct conversion RF transceiver (2) and ASIC having an on-chip voltage controlled oscillator operating frequency that is half of the transmitter (4) and/or receiver (6) operating frequency, the VCO (20) being comprised of a plurality of synchronized LC oscillators (92A-D) introducing precise phase shifts that eliminate frequency ambiguity. The... Agent: Burns & Levinson, LLP
